Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to
worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting
immunostaining in relation to complex human pathologies.
TCR Screening Services
Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.
Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".
Receptor tyrosine kinase which binds promiscuously transmembrane ephrin-B family ligands residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. The signaling pathway downstream of the receptor is referred to as forward signaling while the signaling pathway downstream of the ephrin ligand is referred to as reverse signaling. Cognate/functional ephrin ligands for this receptor include EFNB1, EFNB2 and EFNB3.
Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated. BC = breast carcinoma; HC = hepatocarcinoma.
Immunohistochemical of EphB1 in gastric cancer tissues. a EphB1 protein expressed in normal mucosa at the glandular compartment and in a decreasing gradient from the glandular compartment to the foveolar compartment. b EphB1 protein focally positively stained in well-differentiated gastric cancer cells. c EphB1 protein is focally positive in poorly differentiated gastric cancer cells. d Loss of EphB1 expression in gastric cancer cells.(Provided by Jian-dong Wang,Department of Pathology Nanjing Jinling Hospital/Nanjing University School of Medicine)
EPHB1 Antibody (H970) western blot of T47D cell line lysates (35 ug/lane). The EPHB1 antibody detected the EPHB1 protein (arrow).
Western blot of anti-EphB1 antibody in mouse brain tissue. EphB1 (arrow) was detected using purified antibody. Secondary HRP-anti-rabbit was used for signal visualization with chemiluminescence.
Western blot of lysates from A431, HeLa, MDA-MB-453 cell line (from left to right), using EPHB1 Antibody (H970). Antibody was diluted at 1:1000 at each lane. A goat anti-rabbit IgG H&L (HRP) at 1:5000 dilution was used as the secondary antibody. Lysates at 35ug per lane.
